Published Jul 20, 2025 · Updated Jul 22, 2025
Stored cross-site scripting in Portábilis i-Diário 1.5.0 allows remote authenticated users to execute JavaScript via an SVG attachment. The justificativas-de-falta endpoint accepts an SVG supplied through the Anexo field and serves it so embedded script executes when opened. An account able to upload an attachment and a user who opens it are required, exposing that viewer's session and page data to the stored script.
